Title: Rotary head device
Inventor: YOSHII TETSUJI
IPC: G11B5/588
Filed: 1986-09-19
Abstract: PURPOSE:To obtain a sure head touch and tracking characteristic by driving a head support lever to displace a cunti-lever arm vertically together with the change in the deflection of a head thereby cancelling the deviation of the height of head tip. CONSTITUTION:The head support member 5 supports the head 1 at its head, a piezoelectric element 10 is fitted to a rotary drum 2 and its thickness changes as the applied voltage. In being applied with a voltage varying in response to the rotating position of the rotary drum 2, the element 10 presses down a part 7 to be driven and the head support member 5 is bent downward around a fixed fulcrum point (x) of the mount part. On the other hand, the part 7 to be drive and a head mount part 8 deflect the head 1 upward around a connected part (y) with the head support member 5 and the head rises by a quantity corresponding to the lowered fulcrum (y), resulting in the height of the tip of the head 1 is unchanged and the upward deflection of the head 1 is obtained. Thus, a sure head touch is attained even to a tape 4 whose lower end tends to be floated up.
